For nuclear applications, the Sentry MVS sampler normally is used to collect primary side (RCS) samples for laboratory analysis. However, it also can be used to collect samples on secondary side (PWR) or turbine building side (BWR).

Advantage:

• Non-coring needle design improves septum integrity
• Spring-loaded (deadman’s) shut-off handle helps to protect against overfilling
• Separate fill and vent needles reliably vent vapors
• Simple needle assembly replacement does not require replacing valve or disconnecting piping/tubing
• Variety of sizes and configurations to meet various application needs
• Close-coupled ball valve is specifically designed to minimize dead volume
